Free Trade Area
Free Trade Areas (FTAs) are created when two or more countries in a region agree to reduce or eliminate barriers to trade on all goods coming from other members.
Customs Union

Common Market
A ‘common market’ is the first significant step towards full economic integration, and occurs when member countries trade freely in all economic resources – not just tangible goods. This means that all barriers to trade in goods, services, capital, and labour are removed. In addition, as well as removing tariffs, non-tariff
